This document provides information about RKR-GTSXX reactive power controllers. The controllers measure cos φ value and use microprocessors to automatically switch capacitor banks on and off to maintain the power factor. They have LED displays and buttons to program target cos φ, capacitor on/off delay times, overvoltage protection limits, and automatic or manual mode. The controllers accurately measure capacitor power and switch capacitors as needed to efficiently compensate for reactive power. Safety instructions and connection diagrams are also included.

Reactive Power Controllers


1. INTRODUCTION
Reactive Power Compansation is as of Reactive Power being required for the inductive loads in the A.C systems is
supplied by different techniques/methods. The most common method is well-arranged capacitor groups
accompanied by one Reactive Power Controller which measures cos value; switches on and off capacitor groups
according to required capacitor power, in a central compansation system. RKR-GTS are microprocessor-based
Power Factor Controllers (regulators) with LED screen for Hi-technological control of capacitor banks at 5-7-13
control contacts.

2. MAIN FUNCTIONS
7 Segment LED Display.
Automatic & Manual operations.
Capacitor power measuring.
Auto c/k adjustment.
Auto polarisation (current flow direction).
Over voltage protection via alarm output.
Adjustable capacitor switching on/off time.
Display of voltage & cos values.
Faults indications via LEDs in case of alarm occurance.
Fixed capacitor group output options from 1 step to 5; 7; 13 steps with nonrequired sequencing and adjustment
features.
Direct capacitor switching on/off upon system requirement aimed for serial compensation.

DISPLAY SCREEN VIEW

4. PROGRAMMING
There are 5 menus available for programming of the device via the use of 4 buttons.
Cos : Target cos; adjustable range from 0.80-1.00.
Ton : Capacitor on delay switching: adjustable from 1-120 sec.
Toff : Capacitor off delay switching: adjustable from 1-120 sec.
Uhl : Over voltage protection limit; 240-300VAC adjustable.
Ope : Operation mode; auto/manual.

Cos
Press program button on main menu. Cos is selected via the use of Up-Down buttons and then SET button is
pressed to display the last set value. Program LED will start blinking. The required set value is entered via the use of
Up-Down buttons. Press SET to save. Use program button to exit.

Ton
Press program button on main menu. Ton is selected via the use Up-Down buttons and then SET button is
pressed to display the last set value. Program LED will start blinking. The required set value is entered via the use of
Up-Down buttons. Press SET to save. Use program button to exit.

Toff
Press program button on main menu. Toff is selected via the use of Up-Down buttons and then SET button is
pressed to display the last set value. Program LED will start blinking. The required set value is entered via the use of
Up-Down buttons. Press SET to save. Use program button to exit.

Uhl
Press program button on main menu. Uhl is selected via the use of Up-Down buttons and then SET button is
pressed to display the last set value. Program LED will start blinking. The required set value is entered via the use of
Up-Down buttons. Press SET to save. Use program button to exit.

Ope
Press program button on main menu. Ope (auto/manual) is selected via the use of Up-Down buttons and then
SET button is pressed to select. Program LED will start blinking. The required operation mode is selected via the
use of Up-Down buttons. Press SET to save. Use program button to exit.

5. CAPACITOR POWERS
Test mode must be applied to the device after the required parameters selected correctly. At the end of the test
process the device will show detected capacitors by blinking LEDs of capacitors.

6. OPERATION
6.1.TEST
The defines or corrects the Current Flow Direction during the test mode. Followingly, all capacitor steps are
swiched on and off one by one for computing capacitor power.

6.2.CONTACT TEST
It is assigned to test output contacts of the device when No Current status only is observed. Press SET button for
5 (five) sec. to shift into Contact Test Mode for testing while No Current text is displayed on the screen. Once
this modes activated, device will switch on and off all the contact one by one starting from first step to last. An autostop is to be performed after testing of the last step completed. Device shall not perform a measuring or changing of
the formerly recorded datas while Contact Test Mode status is activated.

6.3.CAPACITOR SWITCHING (ON/OFF)


Device is functionally allocated with very complex capacitor measurement and power determination algorithm.
Capacitor switching on on and off is performed in accordance with the previously determined total reactive power
and the measured capacitors power at the end of ton toff periods. Device effectively detects where and which of
the capacitor is connected because of the required compansation is reached very fastly. Capacitor connection is not
depend on any particular switching order. Switching on and off times are determined by ton and toff times
respectively. User should need to perform a new test whenever any change in capacitors groups or in their order is in
subject.
a) Stepping LED is off permanent; no capacitor connected to this stage and shall not be switched on.
b) Stepping LED blinks; capacitor group connected to the stage, but not yet activated. Upon requirement, it may
be switched on.
c) Stepping LED is on permanent; capacitor is connected and active.

7. ALARMS
7.1.Over Voltage Alarm
If the voltage of line exceeds the value determined by Uov for 4 seconds, device will switch off all the capacitors in a
way to protect against possible damages. While the device is in alarm the voltage will blink on the screen and then
the alarm output will be switched on. Alarm LED also will be on. If the voltage drops 10V below of Uov for 4
seconds device will go out of alarm status and will continue the operation normally.

7.2.Under Conpersation Alarm


If the device switches on all capacitors while cos value is still under the adjusted target cos value for 3 minutes,
the alarm signal will be produced. Alarm relay and LED will be switched on and followingly, the flashing IND
text will be displayed. Returning back to the normal operation will switch the alarm off. Note that the alarm is
activated only in automatic mode.

7.3.Over Compensation Alarm


If device switches off all capacitors while cos value is still higher than of the settarget cos value for 3 minutes
the alarm signal will be produced. Alarm relay and LED will be switched on and followingly, the flashing CAP
text will be displayed. Returning back to the normal operation will switch the alarm off. Note that the alarm is
activated only in automatic mode.
